[Motorola] an oldie but goody question concerning the Expo

[Jeff Kenyon]

That volume knob tends to deteriorate after a while.  When I first got the radio the original knob was on it’s way out, and the current knob is just about gone.  I also know that there was a speaker mic for that unit which I don’t have.
